The effect of Codonopsis ussuriensis on red blood cell(RBC) count in rats was investigated. Among various fractions tested, a significant increase of RBC was observed in animal group treated with ether extract. From the ether soluble fraction, two compounds were isolated and their structures were elucidated as ${\alpha}-spinasterol$ and ${\beta}-sitosterol$ by chemical and spectral analyses.

An hydrocarbon alcohol and steroids were isolated from the hexane fraction of the extract from the seeds of Phaseolus radiatus L. And also a flavonoid was identified from the ethyl acetate and butanol fraction. The structure of the obtained compound were elucidated by spectroscopic methods (UV, IR, mass and NMR) and their physicochemical properties. As the results, triacontanol, stigmasterol, ${\beta}-sitosterol$ and vitexin were identified.

Further studies have been done on the constituents of the tubers of Liriope spicata $L_{OUR}$ (Liliaceae). Four steroidal glycosides, tentatively designated as compounds I. II, III and IV, were isolated from the n-BuOH soluble fraction of this plant. The structures of these glycosides were established as ${\beta}-sitosterol$ glucoside, prosapogenin II of spicatoside A, ophiopogonin B, and prosapogenin III of spicatoside A.

From the root of Symplocarpus renifolius, four compounds were isolated and their structure was elucidated by chemical and spectroscopic methods. They were identified as ${\beta}-sitosterol$ (compound 1), asparagine (compound 2), isocorydine (compound 3) and 3-hydroxymethyl-4-phenyl phenoxy carboxylic acid glucopyranosyl ester (compound 4). These compounds were firstly isolated from roots of Symplocarpus renifolius. Compound 4 was identified as a new compound, named as symplocarposide.

Five known diosgenin glycosides have been isolated from the MeOH extract of Smilax china rhizomes and characterized as prosapogenin A of dioscin, dioscin, gracillin, methyl protogracillin, methyl protodioscin and its corresponding 22-hydroxy analog. This is the first isolation of the former four compounds from this plant. ${\beta}-Sitosterol\;glucoside$ was also isolated and identified.
